Title: Apparatus for the remote synchronization of colour television signals
Inventor: SCHONFELDER HELMUT
IPC: H04N9/475
Filed: 1968-01-03
Abstract: 1,207,541. Colour television; automatic frequency control. FERNSEH G.m.b.H. 3 Jan., 1968 [3 Jan., 1967], No. 456/68. Headings H4F and H3A. To synchronize colour television signal including a chrominance signal switched in phase at line frequency e.g. " PAL " or " SECAM " (Registered Trade Marks) signals, derived from a remote station with signals generated at a central station. Two control voltages and two switching signals i.e. YES/NO signals, are derived by comparing the composite colour signal generated at the central station with the composite colour signal transmitted from the remote station, and these control and switching signals are transmitted from the central station to the remote station to effect synchronization of the remote station. The first control voltage and the first switching signal are derived by frequency and phase comparison between the horizontal and vertical synchronizing impulses respectively and correspond to any frequency and/or phase differences. The second control voltage is derived by frequency and phase comparison between the chrominance subcarriers, preferably the colour bursts, and the second switching signal is derived by comparing information denotive of the switching phase for line sequential transmission of the chrominance signal i.e. the switching phases of the colour bursts. At the remote station the first control voltage synchronizes an oscillator operating at twice line frequency by means of a reactance circuit, and the first switching signal produces a variation of the horizontal frequency until the correct frame coincidence between the vertical synchronization pulses is attained. The second control voltage readjusts the frequency and phase of the chrominance sub-carrier generator by means of a reactance circuit and the second switching voltage switches over the phase of the remote station coder identification pulse generator if the switching phase of the central and remote station do not coincide. The control and switching signals are preferably transmitted from the central to the remote station by a frequency-division multiplex process employing frequency modulation and using a sound-radio line.

Title: Stabilized transistor oscillators
IPC: H03B5/36
Filed: 1964-01-06
Abstract: 1,034,592. Transistor oscillators. RADIO CORPORATION OF AMERICA. Jan. 6, 1964 [Jan. 9, 1963], No. 602/64. Heading H3T. In a transistor Colpitts oscillator a resistor is connected in parallel with the frequency-determining resonant circuit of such a value as to reduce frequency variations caused by variations in voltage of the supply. In the circuit of Fig. 1, an increase in the voltage E applied at terminal 21 causes the base-emitter voltage to increase and this increases the capacitance between base and emitter but reduces the resistance. Such capacitance increases tend to reduce the frequency of oscillation both by virtue of the added capacitance to resonant circuit 12, 14, 16 and by virtue of the modification in the phase change taking place between base and emitter. The corresponding reduction in base-emitter resistance tends to alter the phase change in the opposite direction and hence compensate the frequency variation. Variable resistor 48 is adjusted so that a minimum frequency change is obtained with supply variations. Inductors 28 and 41 constitute radiofrequency chokes. Figs. 2 and 3 show modified forms of the circuit in which a piezo-electric crystal in series with a capacitor is used as the frequency-controlling element.

Title: Improvements in or relating to valves
IPC: F16K11/074
Filed: 1954-01-08
Abstract: 746,606. Valves. BENDIX AVIATION CORPORATION. Jan. 8, 1954 [Jan. 9, 1953], No. 605/54. Class 135. A valve comprises a casing 25 containing first and second relatively slidable members having contact faces pressed together, e.g. the rotary disc valve 31 secured to its spindle 36, and its seat 30 respectively ; means supporting the valve 31 against movement away from the seat, e.g. the casing coverplate 26 and the ballbearing 34; a casing inner face 33, Fig. 7, at the back of the seat; a fluid passage terminating in a port in both valve and seat faces, e.g. 65, 64, in member 31 and 44 in member 30; a pressure chamber 82 for developing thrust, e.g. through a piston 84 and the face 33 for urging the seat against the valve and having a duct 87 connecting to the seat face in the path of the valve port but spaced from the seat port, e.g. via groove 88, so that fluid flows from the seat port to the pressure chamber only by leakage between the faces when the ports are out of register; the leakage path is shortened by overlap of the valve port with the groove during approach of the ports; the pressure chamber is directly connected to both ports when the valve port overlaps both groove and seat port as shown in Fig. 9; and the leakage path increases in length as the valve port moves over the seat port. Thus the increase, when the ports overlap, in the force tending to separate the discs is reduced and a substantially constant sealing pressure between the discs is maintained in all positions of the ports. When the ports align, or are out of alignment as in Fig. 2, inlet pressure at 20 acts behind a sealing ring 50 around a tube 49 welded to the member 30 and behind a resilient sealing flange 56 on the member 30 so that the leakage pressure between the faces tending to separate them is overcome. At the same time four pressure chambers of which only two, 80, 82, Fig. 7, are shown, are exhausted to outlet 21 via bleed grooves 89 intersecting the grooves 88 and around the unsealed outlet port 43 at 29. Valve 31 has four ports; 60, 61 connected by passage 62, and 63, 64 connected by passage 65; while seat 30 has inlet and exhaust ports 44, 43 and two ports 45, 46 connected to either side of a double-acting fluid motor.
